Trim Pumps - What part numbers for Drives?
 

I uncovered another "challenge" and think I may have identified the source.

What is the proper pump / PN to run the drive trims for SSM 5 (or any SSM setup for that matter), on the old straight bottom Top Guns?

Problem is that I noticed out of the water, the drive trim is extremely slow. Then, underway, I cannot trim the drives up at all. I have been running around for the past few weeks with the drives stuck in the negative trim position / planing position. I cannot even trim to level.

I think that maybe the pump doesn't have enough power to trim the drive "up" while underway. I.E. - it cannot overcome the force of propulsion. Old setup was with TRS, new setup is 5s on boxes. Does the bigger drive setup require a different pump? I am running the pumps that came with the boat / original setup.

I think I am running the wrong pumps......

OR, does anyone have a SSM drive manual they could share that would list the required pumps?

Just went through this 2 weeks ago! ZP helped me get it right. You need number 5 just the pump.

That is assuming you have a weak pump and not a bad relief valve.

Are they plumbed correctly? They are not the same pressure in both directions.

The pressure settings are also adjustable.
